BOTTLE-SEAL.

Specification of Letters Patent.

Application filed April 25, 1910.

Patented Sept. 2, 1 9i 3. Serial No. 557,413.

T 0 all whom it may concern:

Be it known that I, AnoLrrr G. KAUFMAN, a citizeno't' the United States, residing at New York, in the county and State of New York, have invented a new and useful Bottle Seal, of which the following is a specification.

This invention relates to seals for bottles, and especially to seals, in which the cap, or metal part is made of material that can be readily torn, and which is provided with a slotted portion and a pendant part, or thumb piece which may be grasped by the operator for the purpose ofrupturing, the cap sufficiently at the slotted part to readily remove the seal and the object of my invention is to provide a pendant part, or thumb piece, so constructed that the lower end thereof may be readily raised out of contact with the bottle SO that it can be readily grasped by the operator to remove the seal, as described above. In devices of this kind, as the pendant part is made integral with the cap, and as the cap must be made of sufiiciently heavy material to withstand the pressure of the gases Within the bottle, when the cap is mounted on a bottle the pendant part is usually forced into close contact with the neck of the bottle and it is difficult to get the bottom part of this thumb piece far enough from the bottle to be grasped for the purpose of removal.

It is the object of this invention to provide means to weaken the pendant part, or a portion of it sufficiently to enable the operator to readily separate a sufficient portion there of from the close proximity of the bottle to enable the operator to readily grasp the same to remove the seal. A further object being that in weakening a portion of this pendant part, or thumb piece, should the bottom thereof catch on any object, unless.

the pull were a very violent one, the part would be bent at the weakened portion, and, the tearing of the seal at the slotted part and the opening of the bottle thereby would be prevented.

The invention is illustrated in the accompanying drawing in which- Figure 1, is a side elevation of a portion of a bottle with my improved seal applied thereto; Fig. 2, is a central vertical section of a bottle and of a. similar but modified form of seal; and Figs. 3, 4, and 5, are respectively eleyations of other modified forms.

In the drawing, 4, indicates the top part. of a bottle with one of my improved seals 5, applied thereto. As shown the seal comprises a metal cap 6, having a slot 16 and a pendant part, or thumb piece 7, which may be grasped between the thumb and fingers for the purpose of rupturing a portion of the body part of the cap in connection with the slot 16, so that it may be removed from the bottle. As described thus far the seal is in regular commercial use. The slot, or slit 16, may be any perforated, scored, grooved, or otherwise weakened line such as is commonly employed between the body and tearoll' strip of a bottle or can cap of this general type.

In applying seals to bottles the tool or die which secures them in place usually forces the pendant part 7, into close contact with the neck of the bottle, as shown at 7, in Fig. 2; and when it is desired to open the bottle, difficulty is experienced in getting the finger, or thnmbnnder this part to raise it out suiliciently that it may be grasped by the operator with a sufficient hold to enable one to rupture the metal of the cap. Especially is this true where seals are made of comparatively heavy material to withstand the pressure of contained gases, as the pendant part is made integral with the cap, and must be of sufficient width in the body portion thereof to be grasped with a firm hold to accomplish the easy rupturing of the metal.

To render the pendant part, or thumb piece easily separable from the close proximity, or contact with the bottle, I weaken a portion thereof. This may be done by perforating the pendant part transversely, which perforations may be in the form of letters, as shown at 8, in Fig. 1; or by swaging whereby a thin portion is formed, as shown at 9, in Fig. 2; or by slotting, as shown at 10, in Fig. 3, or by providing a single row of perforations, as shown at 11, in Fig. 4:; or by reducing the width of the bottom part, as shown at 10, in Fig. 5; or the weakening may be done in any well known manner, and may extend straight. across the pendant part, or in curved, or other lines, as may be desired, the object being to so weaken a portion of the pendant part that the bottom, 12, thereof, may be caught with the thumb, or finger nail and raised out from the bottle, as indicated in dotted lines in Fig. 2, .when a suflicient hold :ening a portion of the pendant part, should the bottom thereof get caught on any object while handling the bottle, or in transport- 'ing the same, this part would be bent out-, .wardly without tearing the lotted part of the seal, and the seal would not be torn from the bottle, since the mere strikin of any object would not engage the pen ant part with the same force that would be exerted thereon by an operator in tearing the seal from a bottle; and the force of a blow would. not he usually communicated beyond the weakened point, or portion. It will thus be seen that l have not only provided means to more readily remove a seal from a bottle by the use of the hands alone; but have also provided means to protect seals of this kind from being removed by accidentally coming in contact with an object.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent of the United States, is:

A bottle seal comprising a cap and an in tegral pendant portion, a slit arranged in the line of juncture between said cap and pendant portion and extending inwardly from the marginal edge of the cap, parts of the pendant. portion intermediate the opened end of the slit and the free end of the pendant portion being weakened.
